Hi Team,
we are using the AM26LV32 a a comparator and have difficulties calculating the threshold voltages.
The circuit is the following:
The upper comparator has a positive switching threshold (at the +input) and is normally 1 when Uin is 0 V. This switching threshold has been correctly calculated and measured.
The lower comparator has a negative switching threshold (at the + input) and is normally 0 at a Uin of 0 V. This switching threshold was measured at -2.04 V but I am not able to calculate this threshold value.
If I take the feedback resistor of 82 kohm in parallel with R68 2.7 kohm (since the output is at 0 V), I don't get the measured threshold.
Am I missing something in the circuit or with the AM26LV32?
Thanks for your support.
Regards,
Alen
